Postcard grading scale used on Old Photographic

M - Mint: A perfect card just as it comes from the printing press. No marks, bends, or creases. No writing or postmarks. A clean and fresh card. Seldom seen.

NM - Near Mint: Like Mint but very light aging or very slight discoloration from being in an album for many years. Not as sharp or crisp as Mint.

EX - Excellent: Like mint in appearance with no bends or creases, or rounded or blunt corners. May be postally used or unused and with writing and postmark only on the address side. A clean, fresh card on the picture side.

VG - Very Good: Corners may be a bit blunt or rounded. Almost undetectable crease or bend that does not detract from overall appearance of the picture side. May have writing or postally used on address side.

G - Good: Corners may be noticeably blunt or rounded with noticeably slight bends or creases. May be postally used or have writing on the address side.

FR - Fair: Card is intact. Excess soil, stains, creases, writing, or cancellation may affect picture. Could be a scarce card that is difficult to find in any condition.
